  • Mercaptan odor control - case study

    Background In municipal and industrial waste treatment, hydrogen sulfide is not the only offensive gas generated from anaerobic decomposition. Mercaptans (RSH) are the organic equivalent to hydrogen sulfide and more odorous at 1/1000th the concentration. Mercaptans are naturally occurring from the degradation of sulfur containing organics (proteins, etc.).   A table of ...

  • Application of Biotrickling Filter for Odor Control at The Morris Forman Wastewater Treatment Plant

    Pilot-scale study of a biotrickling filter using synthetic, high surface area media was undertaken by MSD Louisville, with the intention of saving the high cost of operating thermal oxidizers. Currently, two recuperative thermal oxidizers are used to treat odorous emissions from various sources. The pilot study showed that it is possible to treat hydrogen sulfide and organic sulfur compounds at ...

  • Online Odors Monitoring in Waste Water Treatment Plants

    Odors are very distinct air contaminants as they generate nuisances (see note at the end). The factors playing a role in the determination of odor annoyance are : odor concentration and intensity, frequency, appreciation, duration, synergy and location. Chromatotec proposes an automated solution to well identify the origin and the level of odors. Technology Description We offer a ...

  • Advancing Odor Control to New Levels Gurnee Sewage Treament Plant North Shore Sanitary District

    ABSTRACTThe North Shore Sanitary District (District) owns and operates a 24-mgd sewage treatment plant located in Gurnee, Illinois. Frequently, odors from the two-stage activated sludge plant’s solids handling facilities made their way into the adjacent residential neighborhood. A new two-stage odor control system for the plant’s solids handling facility was put on-line in October 1999. This ...

  • Helping Laurel Asphalt to Fight Foul Odors and Be Good Neighbors

    One of the unavoidable byproducts of the asphalt production process is a mixture of volatile hydrocarbons, mercaptans, hydrogen sulfide, and heat, which may cause a unique mixture of foul odors. When this happens, many asphalt producers have to contend with neighboring residents – often homes and businesses – that bring their odor complaints to both the media and local town-hall ...

  • A Comparison of an Organic Biofilter and an Inorganic Biofilter for the treatment of Residual odors emanating from a Biosolids De-Watering facility

    The following paper is a comparison of an organic media biofilter and a synthetic media biofilter for the treatment of residual odors emanating from the operation of a biosolids dewatering and truck loading system at the City of Toronto's Ashbridges Bay Treatment Plant. The system compared was an in-ground, header/lateral system operated in a forced draft, up flow, open top configuration. The ...

  • Case study - Bi-On Carb OX: Odor treatment in WWTPs. Case study SIMTEJO (Portugal)

    Avoiding problems associated with foul odors in and around collectors and waste water treatment plants is today one of the major focus points to avoid possible issues related to worker safety, as well as minimizing negative social discomforts caused by the foul odors. The main sources that generate foul odors in WWTPs occur at stages of anaerobiosis, where the lack of oxygen favours the ...

  • Innovative Ammonia Control case study

    Ammonia has increasingly become more of a regulatory concern. Ammonia emissions into the atmosphere have been linked to the formation of fine particulate matter, while ammonia emissions in wastewater are restricted because of the negative affect the chemical has on rivers, lake, and aquifers. Many sources of biofuels contain ammonia or can create ammonia during processing. The following case ...

  • Bio-oxidation control of air emissions from panel board production – A new direction

    Biofilters or bio-oxidation systems have been used for control of air emissions, primarily odors, since the 1960’s. Those early uses in the U.S. were largely relegated to odor control, primarily H2S, mercaptans and skatols, from wastewater treatment facilities. The Europeans were more aggressive in applying biofilter systems to various industrial air emissions, again primarily for odor control in ...
